ABB 1SDA066520R1 A1A 125 TMF 100-1000 3p F F molded case circuit breaker

ABB 1SDA066520R1 is a low-voltage molded case circuit breaker from the Formula family. The complete ABB part number is 1SDA066520R1. It is specified for dependable switching and protection against overload and short circuit in distribution panels, control panels, motor feeders, HVAC systems, pump control panels, commercial buildings and industrial installations.

This ABB A1A 125 TMF 100-1000 3p F F configuration combines a 3-pole circuit breaker, a frame rating of 125 A, a current setting of 100-1000 A and a rated short-circuit breaking capacity of 18 kA at 415 V AC. The breaker is fixed and uses a fixed TMF trip arrangement where specified.

The ABB Formula and Tmax families are designed for clear selection by frame size, pole configuration, current setting and Icu/Ics performance. For procurement, replacement and panel-bill-of-materials work, use the exact reference 1SDA066520R1 and the model identifier A1A 125 TMF 100-1000 3p F F to avoid mixing breaker frames, trip units or interrupting capacities.
